Provo-based Ancestry.com has found that Obama's lineage -- on his mother's side -- can be traced to Germany.

Using online sources and microfilm from the Family History Library owned by The Church of Jesus Christ of Latter-day Saints, genealogists found a document that went back to Obama's eighth great-grandfather, Conrad Wolflin, who served as mayor of Orsingen, Germany for 30 years.

Obama's sixth great-grandfather, Johann Conrad Wolflin, was born on Jan. 29, 1729 in Besigheim, Wuerttemberg, Germany and in 1750 resettled in Pennsylvania. changing his name to Wolfley. Told of the Obama connection, current officials in Besigheim, tourist dollars dancing in their heads, jumped for joy.

Besigheim Deputy Mayor Klaus Schremps, whose town is photographed above, told the Associated Press Television Network he tracked down a copy of the parish record himself, and located Wolflin's name.

"If this turns out really to be the case," he said, "we will extend an invitation to Mr. Obama and if he would come and visit at some stage, it would be a great joy for the city and for the people."

This of course is through Obama's mother side, she of Irish and Kansas roots. His father was Kenyan.

If that were not enough to make the president feel welcome, relatives of survivors of Buchenwald Concentration Camp are also calling Obama family.

It seems the president's great-uncle (also on his mother's side), Charlie Payne, 84, helped liberate a sub-camp there when he was an infantryman fighting in World War II.

"The survivors see President Obama almost like a grandson of theirs," Volker Knigge, director of the Buchenwald memorial, told CNN. "The president is related to one of
the brave men who came here and saw the Nazi horror firsthand."
